The unmanned aerial vehicle ground starting device provides power guarantee for unmanned aerial vehicle starting, and is important ground guarantee equipment related to safe and reliable starting of the unmanned aerial vehicle. The unmanned aerial vehicle starting device adopts a working mode of direct power supply output by constant voltage of a power module, namely, the starting device outputs direct current with constant voltage, the starting motor is driven to rotate, and then the starting motor drives the unmanned aerial vehicle engine to start.

Secondly, in the initial stage of engine starting, as the engine rotating speed is zero and the starting motor is in or near a 'locked-rotor' state, the generated reverse electromotive force is zero; the output voltage of the constant-voltage power supply output mode is a constant value, so that the unmanned aerial vehicle engine is in a maximum torque state at the starting moment, and the excessive torque impact can bring serious consequences of damaging the engine shaft and even breaking the shaft. Thirdly, when the unmanned aerial vehicle starts on a plateau with the engine, the output characteristics of the engine are unstable and are easy to change due to the influence of factors such as air, temperature and humidity, and in a working mode of constant-pressure direct output of the power module, even if the input power is sufficient, the phenomenon of overtime stopping in the starting process of the engine can occur.
